[Rhomboencephalitis caused by Listeria monocytogenes: a case studies with magnetic nuclear resonance]

Central nervous system infections due to Listeria monocytogenes result in a variety of clinical syndromes ranging from meningitis to rhomboencephalitis. We report the case of a previously healthy patient with rhomboencephalitis in whom the CT scan was normal, while magnetic resonance imaging (MRI) confirmed the diagnosis. We review the literature and emphasize the value of MRI for timely diagnosis.
